A Family Business, A Global Network
Founded in 1977 and family-owned to this day, Spantech supplies specialty calibration gas solutions worldwide — from our UK head office, with partner offices in Poland, India and the USA.
Our Product Range
Gas Sensors
Electrochemical, infrared and pellistor sensors for toxic, flammable and oxygen detection. A UK distributor of the Citicel and Sensoric ranges.
Calibration Gas
Reactive, non-reactive and complex mixtures in our own-brand cylinders — with the right valve, fill and shelf life for your market, wherever in the world it ships.
Gas Generators
Generate NIST-traceable calibration gas on demand. Cheaper, safer and greener than disposable cylinders for reactive gases such as Cl₂, ClO₂, HCN, H₂S, NH₃, NO and O₃.
Rare Gas Purifiers (RGP)
In-line and portable purifiers and dryers for argon, helium, neon, xenon and krypton — protecting spectrometers, glove boxes and analytical instruments from moisture and CO₂.
Purge Welding Products
Purge dams, bladders, oxygen monitors, purge tape and accessories for high-integrity root welds in stainless, duplex and exotic alloys.
Procurement Services
One purchase order, one delivery, one point of contact. Consolidate cylinders, sensors, regulators and consumables from multiple manufacturers into a single order, with the dangerous goods paperwork handled for you.

Same products, different compliance regimes. Start from your sector and we'll narrow the specification.
Nearly Fifty Years of Getting the Specification Right
The Spantech family business began in 1977 as Spantech International and remains family owned and run to this day. Spantech Products, formed in 1983, has specialised in calibration gas since the mid-1990s and is now a global network — but the way we work hasn't changed: you speak to someone who understands the application before you buy.
Technically Led, Not Catalogue Led
We specify against your detector, your gas, your alarm level and your budget — not against a part number you hope is right.
Own Brands, Independent Advice
Accuspan, Spancan, Spanweld and Spanstop sit alongside the brands we distribute, so we can recommend the honest fit.
A Genuinely Global Network
Partners in Poland, India and the USA, and worldwide supply from our UK head office.
